| Description: | An IMAP TR-FRET assay was used to analyze the enzyme activity (Molecular Devices Corp., Sunnyvale Calif.). 5 L of serial diluted PDE10A (BPS Bioscience, San Diego, Calif.) or tissue homogenate was incubated with equal volumes of diluted fluorescein labeled cAMP or cGMP for 60 min in 384-well polystyrene assay plates (Corning, Corning, N.Y.) at room temperature. After incubation, the reaction was stopped by adding 60 L of diluted binding reagents and was incubated for 3 hours to overnight at room temperature. The plates were read on an Envision (Perkin Elmer, Waltham, Mass.) for time resolved fluorescence resonance energy transfer. The data were analyzed with GraphPad Prism (La Jolla, Calif.). Enzyme Inhibition. To check the inhibition profile, 5 μL of serial diluted compounds were incubated with 5 μL of diluted PDE10 enzyme (BPS Bioscience, San Diego, Calif.) or tissue homogenate in a 384-well polystyrene assay plate (Corning, Corning, N.Y.) for 30 min at room temperature. After incubation, 10 L of diluted fluorescein labeled cAMP or cGMP substrate were added and incubated for 60 min at room temperature. The reaction was stopped by adding 60 μL of diluted binding reagents and plates were read on an Envision (Perkin Elmer, Waltham, Mass.) for time resolved fluorescence resonance energy transfer. |
